Hahahaha.
Where do I even begin. I'll start with the obvious.
They're afraid of continuing to pay decent wages, overtime pay instead of straight pay, paid sick leave, decent hours, bathroom breaks, lunches, comfort breaks, access to drinking water (these cause needless bathroom breaks that waste time!!!), annual leave, maternity leave, pensions, representation if you mess up at work, unions coming between upper management abusing and harassing employees, creating and maintaining a safe work environment.
